GYRUS NEVVHALL, OF HINSDALE, NEV HAMPSHIRE.

' IMPROVEMENT IN HARVESTERS.

Specification forming part of Letters Patent No. 36,017, dated July 29,1862.

To all wiz/0m it may concern.-

Be it known that I, CYRUs NEWHALL, of Hinsdale, in the county ofCheshire and State of New Hampshire, have invented a new and ImprovedGrain and Grass Harvester; and I do hereby declare that the following isa full, l

clear, and exact descriptionof the same, ref erence being had to theaccompanying drawings, making a part of this specication, in which-Figure 1 is a side sectional view of my in` vention, taken in the linexx, Fig. 2; Fig. 2,

Ya horizontal section of the same, taken in the f frame A, and has awheel, C, placed loosely on one end of it, and radial arms D attachedpermanently to its opposite end, the arms D being each provided with aroller, E, at its end, on which a rim, C', which constitutes the otherwheel ofthe axle B, is placed. The rollers E are each grooved at theirperipheries to receive aviiange, a, at the inner side of rim G,

' which secures said rim to the rollers E.

The diameter of the rim C is equal to that of the wheel C, and the rimis allowed to rotate freely on the rollers E, the arms D of which arefixed, in consequence of being attached permanently to the axle B, aspreviously stated.

To the main frame A there is attached by joints b b a frame, F, whichmay be formed of vtwo rods, b b, connected by a cross-bar, d. This frameF extends down between the two lower arms, D D, and projects a shortdistance beyond them. The lower end of this frame F has a shoe, G,attached to it by joints e c, and to this shoe a finger-bar, H, isconnected, the `joints e e admitting of the finger-bar being elevated toa vertical position when the machine is being drawn from place to place,the fingerbar being retained in this position by a catch, c, on one ofthe upper arms, D, as shown in Fig. l.

On the finger-bar H there is placed a sickle, I, which may be of theordinary kind, or such as are used with a reciprocating movement. Thissickle I is connected by a rod, J, with a crank-pulley, K, on the backend of a shaft, L, on the main frame. This shaft Lis rotatedby means 0fbevel-gears f g from a shaft, M, at

shaft L, and are connected with it by clutches N N, said clutches beingoperated by levers O O, rods P I), and a hand-lever, Q, as shown in Fig.2.

The iinger-bar and sickle may be elevated to pass over obstructions,when necessary, by means of a lever, It, and chain S, the latter beingattached to frame F and to the back end of lever It, which is hungloosely on the axle B, and has its front end passing through aperforated segment-guide, T, in which a pin, j, is fitted to retain thelever R at any desired point.

In consequence of having the wheel C ai ranged as shown and described,the finger-bar H may be placed in line with the axle B, as shown in Fig.2, and a direct sickle-driving mechanism obtained. The sickle,therefore, it will be seen, will rise and lfall simultaneously with thewheels C G', and be allowed to conform perfectly with the irregularitiesof the surface of the ground over which it passes, thereby insuring acut of uniform height, while the draft of the machine, owing to thesimple and direct sickle-driving mechanism, is rendered quite light andeasy for the team.

I am aware that the finger-bars of harvesters have been previouslyplaced in line with the axle of the machine 5 but such an arrangement,so far as'I am aware, has hitherto involved the necessity ofcomparatively complicated sickle-driving mechanism, in order .t0 avoidthe off77 wheel of the machine-a contingency which is fully obviated bymy invention.

Having thus described myinvention, what I claim as new, and desire tosecure by Letters Patent, is-'- The arrangement of the frame F,constructed'as shown, with the rim C, shoe G, and the main frame A, inthe manner herein shown CYRUS NEWHALLe Vand described.
